METAL-CONCRETE CONTAINER.

Patented Feb. 6, 1912.

Original application led June 18, 1910, Serial No. 567,572. Divided and this application led August 19, 1910. Serial No. 577.992.

To all whom it may concern Be it known that I, ISAAC A. BnAnnooK, residing at Haddonfield, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Metal-Concrete Containers, of which the following is a specification.

The invention of the present application is a metal concrete structure of more orless general application, and in its generic nature, the' invention resides in providing a I, metal reinforce container that may be used in a. variety of Ways, the invention as illus- `trated, however, being particularly designed for use as a mill for crushing and pulverizing ores. It may be used as a cement burning kiln, as a metallurgical furnace, and in any other Way for which it may be found adapted.

It is one of the objects of my invention to provide a container that may be economically constructed at the place where it is to be used from material available at such place, or that may be readily conveyed to the locality by burros, or other pack animals.

Generically my invention resides in providing a container constructedA of metal hoops,`bands or strips which support a covering of bands of Woven Wire netting, the same being protected on the outside and inside by a Wall of cement, concrete or other like substance, and being further provided, when desired, on its inside with a lining otl rocks. The lining of rocks is set by concrete, plaster, cement. or the equivalent, into the inner lining of the apparatus.

Again, my invention residesin providing a protected 'built up metal construction, whereby the several parts are so tied, connected and interlocked, as to, form a strong and efficient device for whatever use to which it may be put. f l

For purpose of illustration, I have disclosed my invention. asparticularly applied and adapted for use as a metallurgical apparatus for use in crushing, pulverizing and treating ores, although I desire it understood that I do not limit myself to this use.

vmay be the trunk of a tree,

This ap lication is a divisional part of my copending application tiled June 18, 1910, Serial No. 567,572.

The invention also includes those novel details of construction, combination and arrangement of parts, all of which will be first fully described, then be specifically pointed out in the appended claims and illustrated in the accompanying drawings, in which:

Figures 1 and 2 are perspective views, illustrating themethod of construction of the shell or casing of the container or mill. Fig; 3, is a detail sectional perspective view of a part of thc completed structure. Fig. 4, is a central vertical longitudinal section of my complete apparatusdesigned for use in connection with liquid fuel. Fig. 5, is a .cross section on the line 5 5 of Fig. 4. Fig.

6, is a central vertical longitudinal section on a reduced scale showing the arrangement of parts when brush Wood,` or other`similar fuel is used. Fig. 7, is a cross section on the line 7 7 of Fig. 4.

In constructing my apparatus, I take a suitable mandrel `(when my invention is to be constructed at the mines the mandrel or any other suitable thing that comes handy) and provide a set of hoops, rods, wires or bands 2, bent into the required shape and place them on the-mandrel, as indicated in' Fig. 1 of the drawings, tying the same together by tie wires 3, wherever th'e hoops, etc., cross, with the ends 4 of the tie wires projecting inwardly. A sulicient number of hoops, etc., 2 (hereinafter termed the frames are used to afford the desired strength and support, upon which the frame cover 5 is wound. The cover 5 consists preferably of a band or strap' of woven Wire wound onto the frame, as shown vin Fig. 2, of the draw` ings, in a manner similar to the Way. in which a ball of cord is Wound around a stick.

The cover 5 is tied together where desired,l

by tie wires 6 whose ends may also project inwardly.

The mouths of the container Aare formed of a double thickness of Woven Wire7 Wound around the mandrel 1 and tied to the body portion by the wires 8.

After the frames 2 have been set up and tied, and after the covering 5 has been wound on and after the mouth tubes 7 have been wired in place, the mandrel 1 is removed in any desired-Way. When the mandrel is the trunk of a tree, and itcannot bel pulled out endwise, it may be burned out- 1f desired.

An outer covering 9 of cement, or a mix-- ture of cement and asbestos, or the like, is placed on the frame covering 5 to a suitable thickness and a lining 10 is placed within the container, which lining 10 is preferably thicker than the covering 9. 'Ihe covering 9 and lining 10 form an outer and an inner Wall of the container Aand are united as an integral mass by the cement which passes through the interstices of the frame 2, and the frame covering 5, thus forming an integral structure of the frames 2, cover 5 and walls 9 and 10. The wire 7 is also covered and lined at 1 1 and 12 by a cover and lining of the same material as used -for the cover :9 and lining "10 of--the container proper.

An inner'lining 13 of -rocks of ,any hard material such 4as flint, etc. (or when such material is -not available, yrocks .of the :ore to be treated =may.bel.used) -is provided, lby cementing the -rocks `13 ,to the .inner wall 10 of the container, vthe .ends41of -the `-vtie wires serving as :na'lcbinding lelements to `assist in holding lthe -rocks :in ,place 'These rocks form the vCrushers .or .crushing surface against which the :ore is .dropped or pounded to effect its .pulverization iin a ,manner more clearlyV s'et Aforthghereinafter.

Suitable .longitudinal --partitions 14 .are provided-within the container and these may be formedfof frames 15.0ffwoven wire suitably tied at 16,:to'the .fra-me 2, and covered with a coating of cementor the-like. The partitions 14terminateshortof the central axis of the apparatus to leave a central free or uninterruptedfpassage 18 from the inlet 18 to-theoutlet 19 of the container (see Fig. 4).

I t will-be observed that the entrant and exit ends 21 and 22 o f the container are of hemisphericalform or shape for a purpose hereinafter elucidated.

The container is mounted on a suitable cradle or other convenient means, formed by rollers 23 'suitably supported at 24, and the container may be turned in any desired manner, asfor-example, by rollers 25 on a shaft 26 thatis mounted in bearings 27 and is driven by a pulley 28 from any convenient source of power (notshown) In theusev of my, apparatus as an ore recovering plant two containers 30 and -31 .tainer 31 are held in heating container, and the other 31, serving as the solution container. In the solution container the crusher lining 13 of ore is preferably omitted. The construction of both containers 30 and 31 is the same, excepting that I preferto make the crushing container 3.0 of an elongated structure, while the solution container has no apparent elongation but is substantially spherical in shape.

When a substantiall true 'globular or spherical container 31 1s used it is preferably provided with a flattened zone 32 at right angles to its axis so that it may be rolled along the ground and still maintain its axis, which runs from the center of the inlet 33 to the center of the loutlet 34, horizontal.

In practice, the outlet 19 of thefirst container 30 and the inlet 33 of the second con'- they being spaced slightly apart, however, to leave an air inletpassage 33 betweentlie two containers, 'the volume of vwhich maybe regulated bythe 'slidable collar.

The soluton 37 may introduced the container 3l in any desiredmanner, 4preferably by .a .pipe 38 which is oiritled' at 39 to be swung o ut'of the -Way whenfthefcon- .tainer 31 is lto be rolled away .from the con'- tainer 30. i'

lVhen the invention is to be used with powdered fuel, coal, coke or wood yand brush. I arrange the ap aratus somewhat'fas indicatedin Fig. 6 of tlie drawin"x'by refence to which it will be observe fuel 40 is introduced into the Icontainer and ablcwer 41 of any approved type is provided to create the necessary draft.

A suitable frame or support 42 is pro- -videuwhich may be used either as a conveni ,uit means on which the ore may be introucedinto the container, or it' may be used as a grate for cord wood, when such is use( for fuel.

I1 operation when it is desired that my invention be used in the treatment of o res bearing precious metals', the ore is introduced into the container 30 and the fuel ignited to raise the temperature within the centaine;` 30 to about 500. I prefer, when possible, to use a liquid fuel burnerv or a burner that will produce a flame somewhat of the type indicated in the drawings,

lwhereby the central passage from the inlet to the outlet will be the heat zone. After the fuel has been ignited to produce the heat zone, the container 30 is set in motion to turn it on its horizontal axis, thus causing the partitions 14 to lift the ore 43 and drop it through the hot blast flame whereby the temperature of the o re will be raised to a y high degree, namely, about 5009 F. and

that the l as -heat to assist the chemical re-action.

i thus cause its water of cryst-allization to be driven off and also cause those volaVl products contained in the ore to be separated therefrom. Any sulfur in the ore is removed in this way. The removal of the volatile products in the ore, while passing through the heat zone causes decrepitation to take place, and the ore becomes porous and soft so that when it contacts the bottom of the container it will be broken and crumbled, the breaking and crumbling action is also assisted by the rolling and tumbling of the ore within the container during its movements,- the heavier and lesser heated ores serving to assist in crushing the softer particles until the ore is reduced to a ne powder or dust. The force of the heated blast serves to cause the crushed particles of ore to gradually work toward the outlet 19 of the container, and as soon as the ores vhave been crushed fine `enough the heated blast will carry the ore particles through the outlet 19 of the second container 31 where the hot ore particles are deposited into the solvent. `The container 3l being provided with partitions44 will serve to agitate the solution within the container 31, and as the hot ore particles are directly deposited in such solution the temperature within 'the con- 30 tainer 31 will be maintained at the desired degree. The air opening between the containers 30 and 31 is so regulated that the temperature within the container 31 will be about 200 or 212 F. so as to prevent the boiling of the solvent and yet allow snflicient As soon as a sufiicient quantity oforc is deposited in the solution in the container 31 the same is rolled away and another container rolled into place in lieu ofthe one rolled away. The container containing the ore in solution that has been rolled away is taken to a suitable place and subjected -to enforced percolation by steam or vacuum, if desirable, as its formation permits of either. After exhaustion of its values the contents thereof dumped out,the container will be ready to be used again, as soon as desired.

VVhle my apparatus as a whole has been particularly designed for nse in the treatment of ores bearing precious metals and the like, it may with slight modifications, that will be obvious to those skilled in the art, be used in the manufacture of cement, or for other purposes than those .(lescribed, and I do not wish it understood that it is intended that my apparatus be merely used for the specific purposes herein described, but its use is not limited, and it may Le used wherever convenient, and for whatever purpose to which it may be adapted.

`By making the containers 30 and 31 of hemispherical form at the ends the re-bound of the dropped ore or liquids will be to-i Aand numerous advantages of the invention ward the center of the containers, and hence the contents ofthe same will not jump out.

'The speed at which the containers are turned on their axiswill depend upon the conditions met with in practice, a slow turn ing, however, being sufficient" to effect the results desired under ordinary conditions.

From the foregoing taken in connection. with the accompanying drawings, it is be` lieved the complete construction, operation will be readily apparent to those skilled in the art to which the invention appertains, and I'desire` it understood that. da not limit myself to the recise ldetails of construction described an disclosed in the drawings and slight changes and modifications may be made to adapt the invention to the various useswithout departing from the spirit of thel invention .or 'the scope of the appended claims." `815 What I claim isz- I 1.
